MERTON H. MCCORMICK, OF LAKE ODESSA, MICHIGAN, ASSIGNOR OF ONE- IIALF TO EDIVIN A. BUSH, OF SAME PLACE.

BROOM-HEAD.

SPECIFICATION forming part of Letters Patent No. 575,571, dated January 19, 1897. Application filed May 11, 1896. serial No. 591,109. (No model.)

To all-whom, it may concern..- represents a side view, reduced, of the com- Beit known that I, MERTON H. MCCORMICK, pleted broom. I acitizen of the United States, residing at Lake In the different views, A designates the Odessa, in the county of Ionia and State of broom-stick, having a tapering extremity a, Michigan, have invented certain newand use- Wherein'is cut an elongated recess a.

Fig. 6 rep- D,) and two similar bars 0. The parts are resent-s a top plan of the upper pairs of screws, assembled in the following manner: The bars yokes, and upper bar in combination, the C are inserted through slots 12 b in the ferstick appearing in section. Fig. 7 represents rule and the stick driven in so that the bars 45 atop plan showingalowerpairof screws upon enter the long recess a. By utilizing this one side of the stick, the threaded end of one method and form of the tapering end of the screw being engaged with the bar, while the stick the bars are tightly grasped and wedged second screw is disengaged and turned outin place, the ferrule being then fastened by ward in order that one division of brooma pin or screw b (See Fig. 5.) It is obvious 5o straws may be placed in position; and Fig. 8 that the tapering end of the stick might be driven into the ferrule without being recessed and that orifices might be later formed through the stick to correspond with the slots 1) b for the reception of the bars C; but

the first-stated mode is the more efficient. Let any two screws now be taken and passed through elongated orifices d in a yoke D, the bend of the yoke being placed outwardly. Under these conditions if a threaded end of one clamping-screw be caused to engage the correspondingly-threadcd orifice of a bar 0, as shown in Fig. 7, it will be found that the second screw may be moved outwardly and away from the first. Each pair of screws when combined with yokes and bars, as indicated, is susceptible of being so moved, and it will be readily understood that if a division of broom-straws F be placed between the members of the pairs of screws upon one side of the ferrule and those screws set up within the bars the straws may be subjected to a great clamping effect, from which it would be practically impossible to loosen them except by removing the pressure of the screws. Ordinarily I arrange the clamping-screws E as shown in Fig. ti, causing one screw E of a couple attached to the same yoke D to engage upon one side of the stick the upper of the pair of threaded orifices c in a bar 0, while the second clamping-screw of the couple is inserted in the lower of orifices c of same bar upon the other side of the stick. \Vhen both divisions of broom-straws are clamped upon opposite sides of ferrule and stick, the straws may be evenly arranged at the sides and the upper ends rounded, as shown in Fig. 8, although this formation can obviously be varied within the scope of my invention.

1 am aware that it is not new to attach broom-straws to sticks by the pressure of screws, and I do not claim that feature broadly.

What I do claim, and desire to protect by Letters Patent of the United States, is

1. In a broom-head, the combination of a stick having a tapering extremity, a tapering ferrule B, having suitable orifices, and bars 0 having pairs of threaded orifices near each end, said stick having its substance cut away to permit the passage of said bars, yokes having elongated orifices near each end, and clamping-screws E adapted to be passed through the elongated orifices of said yokes and to engage the threaded orifices in said bars, substantially as described.

2. In a broom-head, the combination of a stick having a tapering end provided with a longitudinal recess, a, a tapering ferrule having suitable orifices, bars G having pairs of threaded orifices near each end, yokes having elongated orifices near each end, clampingserews E adapted to be passed through the elongated orifices of said yokes and to en.- gage the threaded orifices in said bars, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

MERTON II. MCCORMICK.
